I looked at the current errmsg file They go all the way to 255, so I’ll have to scan through it and see what gaps exist.

If nothing else, we find an error code that is not usable on the 6809 version. Later OS-9 added more fields and such in the header, with errors associated with one of those, so it might be fine to hijack something there.

Linking to an executable to use it as a subroutine module, yes? I can see that.
